Maintenance
Checking, Cleaning or Replacing the Air Filter
Operating the machine without a functional air filter may cause severe engine damage and will void
any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken as fuel
system problems. Check the condition of the air filter before adjusting engine idle speed, where applicable. •
If the air filter is damaged (torn, broken, disintegrating), replace it.
The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal
damage to it. The air filter requires regular maintenance as per the maintenance schedule.
Air Filter Inspection and Cleaning
Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as necessary. To
clean air filters:
•
For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.
•
Clean all other air filter assembly components using water and mild detergent, then dry them.
•
For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to spread
the oil through the filter material and remove any excess oil.

Cleaning the Fuel Filter
Remove fuel from the tank and store it in an approved container before starting this procedure.
1. Open the fuel cap to slowly release any pressure in the fuel tank, then remove the cap.
2. Use a piece of wire to hook the fuel tube/filter (

), then pull the filter from the tank.
3. Remove the fuel filter from the tube with a twisting motion.
4. Ensure that the fuel tank vent (

Never operate the blower without the fuel filter. Internal damage could result.
